New Delayed Release Valproate Therapy in Small, Easy-to-Swallow Soft Gel Capsule to be Available in August 2008

MIAMI -- Noven Pharmaceuticals, Inc. (NASDAQ:NOVN) today announced that the U.S. Food and Drug Administration (FDA) has approved Stavzor[TM] (valproic acid delayed release capsules) in 125 mg, 250 mg and 500 mg strengths. Stavzor is approved for the treatment of manic episodes associated with bipolar disorder, as monotherapy and adjunctive therapy in the treatment of patients with complex partial seizures that occur either in isolation or in association with other types of seizures, and for prophylaxis of migraine headaches. The product will be marketed and sold by Noven Therapeutics, LLC, Noven's specialty pharmaceutical subsidiary, and is expected to be available in pharmacies in the second half of August.

Stavzor soft gel capsules are small (up to 40% smaller than Depakote([R]) and Depakote ER([R]) tablets at the 500 mg dosage strength) and easy to swallow, with an advanced enteric technology designed to reduce reflux and gastric irritability. Banner Pharmacaps Inc., Noven's development partner for this product, developed Stavzor using its EnteriCare[TM] enteric soft gelatin capsule delivery system, and submitted the Stavzor New Drug Application to the FDA.

"Valproate, the active ingredient in Stavzor, is recommended by the American Psychiatric Association as a first-line therapy for patients living with bipolar disorder and experiencing manic episodes," said Dr. Miguel Martelli, a psychiatrist in private practice in Georgia. "The small size and soft gel capsule formulation of Stavzor should make this new product easy to swallow, which in my experience is critical to helping valproate patients start - and stay on - their medication."

"Our research indicates that valproate patients would prefer a small, soft gel capsule - like Stavzor - that is easy to swallow," said Anthony Venditti, Noven's Vice President - Marketing & Sales. "In a recent survey of 400 valproate users, more than two-thirds reported difficulty swallowing their other valproate medications, and 85 percent said they would have preferred a small soft gel capsule had it been available when initiating therapy. These are some of the patients who we expect to help with the launch of Stavzor."

"The approval of Stavzor is an important development for patients who use valproate products and for our company," said Peter Brandt, Noven's President and Chief Executive Officer. "For patients, it represents a new, easy-to-swallow treatment option that may help with compliance. For Noven, it represents a significant step toward our goal of establishing Noven as a high-growth specialty pharmaceutical company."

Important Product Safety Information about Stavzor

Valproate products should not be administered to patients with hepatic disease or significant hepatic dysfunction. Hepatic failure resulting in fatalities has occurred in patients receiving valproic acid and its derivatives, usually during the first six months of treatment.

Valproate may produce teratogenic effects in the offspring of women receiving the drug during pregnancy. Benefits of valproate should be weighed against risk of injury to the fetus in women of childbearing potential.

Cases of life-threatening pancreatitis, some rapidly progressing to death, have been reported in both adults and children receiving valproate. Valproate is contraindicated in patients with known urea cycle disorders (UCD), a group of uncommon genetic abnormalities, due to reports of sometimes-fatal cases of hyperammonemic encephalopathy. Concomitant administration of valproic acid and topiramate has been associated with hyperammonemia with and without encephalopathy.

The frequency of adverse effects, particularly elevated liver enzymes and thrombocytopenia, may be dose-related. Multi-organ hypersensitivity reactions have been reported after the initiation of valproate therapy. In a clinical trial of valproate in elderly patients with dementia, some patients taking valproate experienced somnolence, sometimes requiring discontinuation.

Common adverse events (greater than 5 percent incidence) associated with valproate in clinical studies were nausea, somnolence, dizziness, vomiting, asthenia, abdominal pain, dyspepsia, rash, diarrhea, increased appetite, tremor, weight gain, back pain, alopecia, headache, fever, anorexia, constipation, diplopia, amblyopia/blurred vision, ataxia, nystagmus, emotional lability, thinking abnormal, amnesia, flu syndrome, infection, bronchitis, rhinitis, thrombocytopenia, ecchymosis, peripheral edema, insomnia, nervousness, depression, pharyngitis, dyspnea and tinnitus.
